Skyalo does not provide an unlimited data eSIM for Nauru. The available plans are fixed data bundles, such as a 20GB plan valid for 30 days, a 10GB plan also valid for 30 days, and a 10GB/day plan that is usable for 1 day. These bundles include tethering where noted and, for the 10GB/day option, a reduced speed of 384kbps after the data cap is reached.
Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user is an extremely heavy data consumer who would benefit from a truly unlimited option.
